Abstract
Full wavefield migration (FWM) is an inversion-based seismic imaging method that aims at using the complex wavefields in illuminating the subsurface. Instead of simply propagating a source-side wavefield, as in Primary Wavefield Migration (PWM) method, FWM utilizes the complex wavefield that also includes all transmission effects and all kinds of multiples. This is done by a modeling scheme that considers reflectivity as a scattering generator. The additional advantage of such method is that, although a smooth background migration velocity is used, all the scattering can be still generated, which is not achievable by using finite-difference or finite-elements modeling tools. In this paper we consider the three-dimensional extension of the mentioned algorithm. One of the additional challenges of the 3D extension is the memory usage. Therefore, we consider the implementation of blended acquisition.
